Description

thermos bottle stopper

technical field

The utility model relates to the field of daily necessities, in particular to a thermos bottle stopper.

Background technique

The sealing of the mouth of a traditional thermos bottle usually adopts a combination of setting an inner cork inside the bottle mouth and an outer bottle cap outside the bottle mouth. When pouring hot water, you need to open the outer bottle cap first, and then pull out the inner cork. It is troublesome to pour water, and the hand is in contact with the inner cork, which is not conducive to the hygiene of the thermos bottle. When the thermos bottle is overturned on its side, the seal of the thermos bottle will cause excessive pressure inside the bottle, which is easy to burst and has poor safety. In order to overcome the shortcomings of these traditional thermos bottle plugs, a thermos bottle plug including a hollow main body and a cylindrical body has appeared. A movable sphere is provided in the inner cavity of the thermos bottle plug, and a concave arc surface matched with the sphere is provided at the bottom of the cavity. , but this thermos bottle plug is sealed because only the bottom of the main body is provided with the cooperation of the concave arc surface and the spheroid and the main body is made of plastic material, and the fitting of the concave arc surface and the spheroid is not tight, which affects the thermal insulation of the thermos bottle.

Contents of the invention

The technical problem to be solved by the utility model is to provide a thermos bottle stopper which is convenient for pouring water and has good sealing and heat preservation performance.

The technical scheme adopted by the utility model to solve the above-mentioned problems is: a thermos bottle plug, including a cover body with a cavity, and the lower part of the cover body is provided with a cylindrical plug for water sealing with the thermos bottle body and communicating with the inner cavity of the thermos bottle. body, the side of the cover body is provided with a water outlet that communicates the inner cavity of the cover body with the outside world, and a sealing mechanism for isolating the cavity and the inner cavity of the thermos bottle is provided in the cylindrical body, and the sealing mechanism includes a The movable ball inside and the sealing ring fixed on the inner wall of the cylinder are made of elastic material and cooperate with the ball. The sealing ring includes a concave arc surface, and the sealing ring also includes a The sealing ring is a first sealing ring extending radially inward, and the inner diameter of the first sealing ring is smaller than the diameter of the sphere.

Compared with the prior art, the utility model has the advantages that: when using the thermos bottle stopper to pour water, tilt the thermos bottle so that the ball moves out from the sealing ring, and then the water can be poured, the process is convenient, and when the thermos bottle is placed vertically, the concave arc surface supports Hold the sphere to form the main body seal, the sphere continues to press down on the first sealing ring, and the first sealing ring assists in sealing to achieve better sealing and heat preservation effects.

As an improvement of the utility model, a second sealing ring is provided at the lower part of the first sealing ring, and the inner diameter of the second sealing ring is smaller than the inner diameter of the first sealing ring. Through the improvement, when the thermos bottle is placed vertically , the sphere presses down the first sealing ring until it abuts against the second sealing ring, and the second sealing ring further assists in sealing, so that the thermos bottle plug has better sealing and heat preservation effects.

As another improvement of the present invention, the height of the cavity in the cover body is smaller than the diameter of the sphere. Through the improvement, when the thermos bottle is tilted, the sphere rolls out from the sealing ring and gets stuck in the cavity, and the mouth of the thermos bottle is not completely Open, so that the thermos bottle stopper has a better thermal insulation effect.

As another improvement of the present utility model, the outer wall of the cylindrical shape is covered with a plugging sleeve made of elastic material, and the outer circumference of the plugging sleeve is provided with a plurality of blocking rings extending radially outward along the plugging sleeve. The blocking ring is in interference fit with the inner cavity of the thermos bottle. Through the improvement, the thermos bottle plug and the inner cavity of the thermos bottle are easily matched, and multiple blocking rings are matched and sealed to ensure the sealing and heat preservation performance of the thermos bottle plug.
